Fulham boss Roy Hodgson says retirement should not be on the agenda for 37 year-old goalkeeper Mark Schwarzer.
Hodgson believes time is still on Schwarzer's side.
"Some of the best goalkeepers in the past have gone on to over 40," he said.
Schwarzer, who spent 11 years at Boro, said: "I'm enjoying myself more than ever, and I'm probably close to being as fit as I've ever been in my whole career.
"I want to keep going as long as I can. As long as I'm enjoying it, and able to play at this level, why not?"
